Hi,

I try to use curl with sftp through a socks proxy as follows

curl --socks5 socks-server -u user -v sftp://shell.sf.net

but it crashes because the sftp_handle is 0.

(gdb) where
#0 libssh2_sftp_write (handle=0x0, buffer=0xbfa5ea00 "\005\001", count=3)
at sftp.c:1330
#1 0xb7ee0761 in Curl_sftp_send (conn=0x80773f0, sockindex=0,

#7 0x0804f803 in main (argc=Cannot access memory at address 0x3
) at main.c:4692

I use:

/opt/curl/bin/curl -V
curl 7.18.2 (i686-pc-linux-gnu) libcurl/7.18.2 OpenSSL/0.9.8a zlib/1.2.3
libssh2/0.18
Protocols: tftp ftp telnet dict ldap http file https ftps scp sftp
Features: IPv6 Largefile NTLM SSL libz

Is this a known problem and does a fix exist already ?

Thank you
Markus
